The Shark Inside You

This is episode three of Swimming with Shadows: A Radiolab Week of Sharks.

Today, we take a trip across the world, from the south coast of Australia to … Wisconsin. Here, scientists are scouring shark blood to find one of nature’s hidden keys, a molecular superhero that might unlock our ability to cure cancer: shark antibodies. They’re small. They’re flexible. And they can fit into nooks and crannies on tumors that our antibodies can’t.

We journey back 500 million years to the moment sharks got these special powers and head to the underground labs transforming these monsters into healers. Can these animals we fear so much actually save us?
